THE VERTICAL LAND MOTION OF TIDE GAUGE AND ABSOLUTE SEA LEVEL RISE IN BOHAI SEA

We created a reliable dataset of atmospheric water vapor from China's coastal stations (2009–2019), validated against global models and radiosonde data. The study highlights strong links between water vapor and sea surface temperature, aiding understanding of weather, extreme events, and climate change. This dataset supports improved forecasting and climate research.

In this study, long-term tide gauge observations and multi-mission satellite altimetry data were used to investigate the spatial distribution of the long-period tidal contribution in Chinese seas and analyze the relative long-period tidal contribution rate into four regions. The result indicate that the long-period tidal constituent cannot be neglected in the establishment of the LNLW datum to improve tidal datum precision.
